Answer:

C. 195ft²

Step-by-step explanation:

First find the area of the semi-circle:

A = πr²

The radius is 5 (half the diameter)

Plug in the numbers using 3.14 for pi:

A = 3.14(5)²

A = 78.5

Halve the area so you get the area of half a circle:

78.5/2 = 39.25

Now find the area of a trapezoid:

$A = \frac{a+b}{2} h$

Plug in the numbers:

A = 10+16/2*12

A = 156

Lastly, add the area of the semi-circle and trapezoid together:

39.25+156 = 195.25ft²

vova2212 [387]

Answer:

25% of 80 is D. 20kg

Step-by-step explanation:

50% of 80 is 40 and we know that 25% is half of 50%, so half of 40 would be 20.

So, the answer is D. 20kg

The equation for line r can be written as y=-1/4x+3. Line s which is parallel to lone r includes the point (-4,3). What is the e

MaRussiya [10]

Answer:

$y=-\frac{1}{4}x+2$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope of line S using line R (m)

$y=-\frac{1}{4} x+3$

We can identify clearly that the slope of the line is $-\frac{1}{4}$ , as it is in the place of m. Because parallel lines always have the same slope, the slope of line S would also be $-\frac{1}{4}$ . Plug this into $y=mx+b$ :
